Avalanche advisory

Good morning, this is Evelyn Lees with the

Current Conditions:
A delightful day is dawning in the mountains, with mostly clear skies, very light
winds, and temperatures in the mid teens.
Excellent powder remains on the shady slopes, with the crusts on the sunny
slopes varying from place to place depending on how much sun the slope has received.
Avalanche Conditions:
There was a skier triggered slide yesterday
on Gobblers
Knob, on a northwest facing slope at 9800’.
It was about 100’ wide, a foot deep, and long running. It occurred mid afternoon, shortly after the
sun had intensified, and heating was likely a factor. Today, with mostly sunny skies and warming
temperatures in the forecast, the danger of wet sluffs and slabs will increase
as the snow heats up. This will first occur
on east and southeast facing slopes, then continue its
way around the compass all the way to northwest. With the sun much higher in the sky, even “shady”
slopes will be affected.
There were also several
reports of slope cuts releasing sluffs and shallow soft slabs in the snow from
the last storm. These were mostly manageable,
but some were large enough to take you for a ride. And finally, it may still be possible to
trigger a deeper slab avalanche in isolated places. Explosive control work in the Cottonwoods and
Bottom Line (
The
avalanche danger is MODERATE on slopes
steeper than about 35 degrees, with both loose sluff and slab avalanches possible. The danger of wet sluffs and slabs will increase
significantly throughout the day. On
slopes less steep than about 35 degrees, the avalanche danger is generally LOW.
Mountain Weather:
High pressure will
bring dry and warm weather to the Wasatch mountains today. Skies will be mostly sunny, with highs
reaching into the mid 20’s at 10,000’ and the mid 30’s at 8,000’. The southwesterly winds will be light, less
than 10 mph. After a clear, calm night,
the next Pacific storm system will start to affect northern
